Abstract: A method and a device used in an optical wireless communication (OWC) system are provided. A transmitting terminal transmits a plurality of reference signals to a receiving terminal through each of a plurality of beams. Each of the plurality of beams may have an inhomogeneous polarization beam pattern. The receiving terminal measures signal strength and polarization with respect to the plurality of reference signals. When the receiving terminal transmits feedback information including the measured signal strength information and polarization information to the transmitting terminal, the transmitting terminal may select at least one beam among the plurality of beams on the basis of the feedback information. Alternatively, the receiving terminal may select at least one beam from among the plurality of beams, which corresponds to at least one inhomogeneous polarization beam pattern among a plurality of inhomogeneous polarization beam patterns, on the basis of the measured signal strength and polarization.
